JDM motor madness!
 

Im trying to gather some info on older jdm ej20x engines. I've read some info that some blocks were closed, some not. I guess im just fishing for info on older wrx engines, sti v 2 - 7, major differences, etc..

Thanks,
AspenGC8

hopefully, i'll be getting this 2morrow....ej20 motor in 2001 2.5 RS

Doh! My bad... ;)

Version 7 is not even closely the same as Version 4-6. If you make JDM motor comparisions V7 motors are completely redesigned internally while V4-6 are more similar.

meaning 4-6 internals are not as stout, and the cams not as aggressive?

No, just saying that they cannot be put in the same category as the Version 7 motor because the Version 7 motors are different in many ways. The general idea is the same. The motor is itself is different.

this site has a lot of info on the different models

The best two pages ive found about JDM motors:

The old EJ20G's are closed deck, but have hydrolic lifters in the DOHC heads. The best heads are the V8 spec-c heads. The best blocks are probably the Legacy Turbo 2.2's actually.

i think his block in his ej20g is alittle better than the ej22t because the pistons are forged and not cast but your right about the heads

I was talking more about the block design than the pistons, because the closed deck ej22t has oil squirters and just in general can put out more power more reliably for a turbo application.

Why was the dash out of that car? Just Curoius. We never take the dash out when we do wrx motor conversions. EJ20 in a GC8 sure hauls butt thought!
